SPECIFICATION forming part of Letters Patent N0. 698,625, dated April 29, 1902.

Application filed January 14, 1902. Serial No. 89,739. (No model.)

present application relates to the class of me tors in which the delivery is indicated by the number of revolutions of a turbine traversed by the liquid to be measured. It is characterized by "the application to the axle of the turbine of a centrifugal regulator acting upon a valve of special form, which more or less opens the discharge-orifice, according as the delivery is greater or less. This apparatus may be applied to the control of the delivery of various descriptions of cocks, either for Water orfor other liquid contained in vats, tuns, bidons, due.

The invention is illustrated in the accompanying drawings, in which Figure 1 is an axial verticalsection through the turbine; Fig. 2, a horizontal section on the line 1 2 of Fig. 1, and Fig. 3 a front view of the regulator.

The turbine A is preferably of aluminium. It is fixed to the vertical shaft B and rotates within the interior of the closed chamber 0, carried by the cock D, screwed on the conduit or on any vessel containing the liquid. The outlet-orifice L of this cock is bent (see Fig. 2) and directed tangentially onto the turbine A. Its delivery is regulated by a screwed pointed pin 0.

The shaft 13 above the turbine is fitted with the regulator H, the ring P of which is connected by small connecting-rods N N, which pass through the body of the turbine to a valve F, which closes an orifice communicating with the chamber K, whence the liquid flows through the spout E. The regulator comprises, besides the weighted arms H, a bracket or ring H to which the said arms are pivoted, and the links H, connecting the Weighted arms with the ring P.

The valve F is provided with a circular groove within which the connecting-rods N N 4 pass, and this groove allows a certain amount of vertical play or lost motion, so that the valve is only raised by the ring P ofthe regulator when the latter has commenced to rise. The shaft B is carried at its lower end by a screw-point I, the height of which can be regulated and the head of which is covered by a cap G to prevent the regulation being interfered with. At its upper part the shaft B passes through the head of the chamber 0 and enters the bOX M, containing the counting apparatus, which it operates by the endless screw J.

The operation of the apparatus will be readily understood from the following description:

The liquid passing through the orifice L, after the opening of the cock, operates the turbine, which, by reason of the compression of air in the chamberO, commences to rotate before the valve F is raised. Then the regulator rotating with the turbine raises the valve F in proportion to the speed of the turbine--that is to say, with the delivery of the cock--and the How will continue with the speed due to the pressure of arrival. The pointed pin 0 serves to limit the maximum delivery of the meter according to the conditions of subscription. When once regulated, it can be sealed by any suitable means.

It is to be remarked that in this apparatus no delivery can take place before the turbine is in motion, while in ordinary turbine meters a small stream of waterlcan be passed, which is insufficient to operate the turbine,but which will furnish in a given time important quantities of water which escape measurement.

Having fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In a liquid-meter of the turbine class, a turbine, a regulator revolving with theturbine and operating a valve which opens the discharge-orifice in proportion to the'quantity delivered and which at rest completely closes this orifice, the putting in motion of the turbine on the opening of the cock being permitted by the compression of air in the turbine-chamber.

2. In a liquid-meter of the turbine class, the combination with a cock of any suitable char acter of a closed chamber containing the turbine, a centrifugal regulator mounted on and IOU rotating with the turbine-shaft, a valve opthe latter, and a screwed pointed rod control- 10 erated by connections from the regulator, a ling the cock-outlet, substantially as herein 7 play or lost motion existing between the conset forth.

nections from the regulator and the valve, an In Witness whereof I have hereunto set my 5 opening forminga seat for the valve and comhand in presence of two witnesses.
